Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity High
Score 7.2/10


Buffer overflow in the CreateDIBPalette function in win32k.sys in Microsoft Windows XP SP3, Server 2003 R2 Enterprise SP2, Vista Business SP1, Windows 7, and Server 2008 SP2 allows local users to cause a denial of service (crash) and possibly execute arbitrary code by performing a clipboard operation (GetClipboardData API function) with a crafted bitmap with a palette that contains a large number of colors.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
